Hello,

QnA Reputation is something that is scored by answering questions and receiving ratings from other users on your answers. This is so you can visually see who's not only active in the community, but has also been genuinely helping people on the site.

The coins are points that are earned for being active on the site by performing certain actions.

The amount of points you have determine what rank you are.

Passing Stranger - 100
Familiar Face - 1000
Common Friend - 10,000
Confidant - 25,000
Life Partner - 100,000

There are also other achievements that appear as badges on your profile page that appear after you've performed a certain amount of actions.

All of these things are ways you can tell if a user is a regular on the site and how active they've been. If you ever need someone to talk to about your problems, try messaging one of the most active users, they're bound to help you as much as they can :)

I think you mean QNA, and it's the Question&Answer reputation. Basically, how many people have thought your answers were helpful.
The "coins" are just your site points - they're awarded for doing things like answering questions, posting on threads in the forums, joining groups, sending messages, etc. They pretty much just track how much you've done around the site. The ranking is based on that, I believe.

EDIT: Whoops! BlahSupport swoops in to give a proper answer!
